Application filed Getobei 27, 1920. Eerial No. 420,067.

exact description, reference being had to the accompanying drawing, thisspecification.

My invention relates to improvements in forming a part of means forcleaning-fabrics and has particular reference to devicesadapted-to cleanwhat is known in the art as tire liners.

I Une of the objections to the of I111.- chines heretofore used for thispurpose is that after a certain amount of use the edges of the vacuumnozzles-become Worn and roughened whereby the fabric, in being drawnover these nozzles is torn or split. As these fabrics are made in longlengths and as the slightest roughness or tear in a length destroys thevalue of the entire fabric, it is desirable to provide means whereby thedanger of tearing the same is obviated.

It is one of the objects of my invention to provide means whereby thewear on the nozzles may be taken care of and a smooth nozzle surfacealways be provided.

For the purpose of disclosing my inven tion I have illustrated oneembodiment thereof in the accompany drawings in which Figure 1 is a sideelevation of a cleaning apparatus embodying my invention-part of thesame being shown in section;

Fig. 2 is a plan view thereof;

Fig. 8 is a sectional view of one of the tubular nozzles showing thewear plate in position;

Fig. 4 is a perspective view of the wear tube or plate;

Fig. 5 is a sectional view of one of the nozzles showing the modifiedform of wear plate, and

Fig. 6 is a perspective view of one of themodified wear plates.

In the embodiment illustrated, upon a suitable table or bench 1 ismounted a pair of rollers 2 and 3 and these rollers are mounted atopposite ends of the bench and may be removably mounted if desired. Thefabric is wound on one roll, the roll 2, and is unwound. therefrom onthe roll 3, a suit able driving pulley a being provided on the shaft ofthe roll for operating the mechanically.

Extending transversely of the bench and in the path of the fabric as itpasses from one roll to the other, is a cleaning apparatus., Thisapparatus consists, as shown, of a pair of horizontally disposedtransversely roi 1 extending tubes 5 and 6 arranged one in front of theother and one preferably in a lower plane than the other. Each of thesetubes is provided with a longitudinally extending slot 7 in the facethereof. The slot in the-tube 6 is towards the lower portion ofthetubeandthat in the tube 5 in the upper portion of the tube so that asthe fabric is drawn between the tubes, it passes underone tube and thentakes a path upwardly and over the other tube. These tubes preferablytake the form of pipes and are supported in position by suitablebrackets or heads 8 one on each side of the bench.

The opposite ends of the tubes are connected with branch pipes 11 eachof which is closed at one end by a suitable nipple or nut 12; theopposite end being connected to a communicating pipe 13 by suitableelbows 14. One of the branch pipes 11 is provided with a coupling 15 bywhich it is connected by means of a pipe 16 with a suitable vacuumproducing device 17 preferably driven by an electric motor.

In the operation of the device so far. described, the fabric is passedbeneath one pipe and above the other and due to the connection of thevacuum producing device 17 with the two pipes air is drawn through thefabric as it passes over the slots in the pipe removing all dirt anddust from both sides of the fabric, one side of the fabric being cleanedas it passes over the lower pipe and the other side of the fabric beingcleaned as it passes over the upper pipe.

In commercial use it has been found that the edges of the slots 7 becomeworn and roughened so that the fabric in passing over these slots isfrequently cut and destroyed. In order to obviate this difficulty Iprovide separate wear plates for the slots which-may be made ofpolishedsteel or the 1ike,the tubes 5 being generally merely iron pipe,and which may be readily removed from time to time as they wear;

In the embodiment illustrated in Figs. 3

and 4, this wear plate takes the form of a split tube 18 which has theedges of the slot 19 thereof turned back upon themselves as at 20. Thistubular wear plate may be slipped over the nozzles 6 from the end or maybe opened and sprung over the nozzles. The turned back portions 20 fitwithin the slot 6 and turn back upon the inner face 21 or" the slots sothat a rounded edge is provided at the slotted opening in the nozzlesand at the point over which the fabric passes thus providing a smoothsurface over which the fabric may readily slip without danger of beingdestroyed or out.

In the form illustrated in Figs. and ('5, instead of making the wee rplate in. the form of a tubular men'iber I make the wear plate in theform of elongated plates 22 having the rounded and turned in portion 20similar to the portion 20 on the tubular member 18. These wear platesmay be secured on the nozzles in any desired manner as by counter sunkscrews 23.

Having thus described my invention what I claim as new and desire tosecure by letters Patent is:

1. In a device of the character described,

the oon'ibination with a tubular member having an elongated slot thereinwith ODPOSltG' angular edges, of removable means secured to said tubularmember for guarding said edges, said means including portions extendingover and conforming in shape to said member at opposite sides of saidslot and rounded edge portions extending inwardly into said slot andembracing said edges to provide curved guards therefor to prevent damageto the material engaged.

2. In a device of the character described, the combination with atubular member having an elongated, slot therein, of a removablelongitudinally split sleeve adapted to slidably engage said member andto enclose the same, said sleeve having its longitudinal edges roundedand turned inwardly to embrace the edges or the slot in said tubularmember whereby to provide removable, curved wear plates over the edgesof said slot.

In Witness whereof I have hereunto subscribed my name in the presence oftwo witnesses.

EDWIN ROBINSON.
